Use of the "Reference channel of the module":
1
- Channel 0 must be set to "Pt100 climatic" with the temperature unit "Degrees Celsius".
- For each TC channel of this module that is intended to use channel 0 as reference, "Reference junction" must be set to
"Enable".
Use of "Reference channel of group 0":
2
- An RTD channel must be set as "Pt100 climatic" with temperature unit "Degrees Celsius".
- "Reference channel of group 0, 1, 2, 3" must be set as the "Reference junction" of this channel.
- There may be only one RTD channel with "Reference junction active" = "Enable" per group and row.
- For each TC channel of this row that is intended to use this reference, "Reference junction active" must be set to
"Enable".
